        acetabulum
        
        anteversion and retroversion
        
        anteversion
        
        decreased joint coverage
        
        decreased stability
        
        increased likelihood of dislocation
        
        retroversion
        
        overcoverage of the acetabulum
        on the femoral head
        
        acetabulum too far posterior
        
        impingement between acetabulum
        and femoral neck junction
        
        15-20˚
        
        Center Edge Angle of Wiberg
        
        measures acetabular depth;
        viewed from the frontal plane
        
        normal: 25-40˚
        
        dysplasia <16˚
        
        decreases joint stability
        
        possible dysplasia 16-25˚
        
        shallow acetabulum;
        lack of femoral head coverage
    - - head, neck, shaft, greater and lesser trochanters
        condyles, epicondyles
        
        femoral head
        
        angle of torsion
        
        anteversion
        
        angle of torision >15-20˚
        
        toe in
        
        more likely to dislocate
        
        retroversion
        
        angle of torsion is <15-20˚
        
        toe out
        
        increased risk of labral tears
        
        15˚
        
        angle of inclination
        
        115-125˚
        
        coxa valga
        angle of inclination > 125˚
        
        genu varum
        
        increased functional length of the hip abductors
        
        joint dislocation
        
        coxa vara
        angle of inclination < 115˚
        
        genu valgum
        
        increased joint stability
        
        decreased functional length of the abductors
    - - iliofemoral
        
        resists hyperextension
      - pubofemora
        
        resists abduction and extension
      - ishiofemoral
        
        resists internal roation
    - - deepens socket
        provides a seal
      - may play a role in:
        proprioception
        pain sensitivity
        protecting rim of acetabulum
        joint lubrication
- - - - anteversion
    - - retroversion
